SPECIFICATION forming part of Letters Pate nt No. 737,221, dated August 25, 1903. Application filed February 10, 1903. Serial No. 142,769. (No model.)

To all whom it may concern.- Be it known that we, MATHIAS GRAB, WIL- HELMDOBBELSTEIN, andFRIEDRIoH UNTER BEIN, citizens of the German Empire, residing at Haaren, near Aix -la-Ohapelle, Rhenish Prussia, Germany, have invented an Improved Apparatus for Mechanically Greasin g Ropes, of which the following is a specification.

. Hitherto the periodic greasing of running ropes has been done by the workmen applying the grease to the rope by hand and then finishing the greasing by rubbingthe grease into the rope. This is a time-wasting as well as a troublesome work, which can be done mechanically by means of the apparatus described hereinafter. e

In the annexed drawings, Figure 1 is a ver-' tical section of the apparatus. Fig. 2 is an elevation of the same for a case where the rope to be greased is running in a horizontal direction. Fig. 3 is a vertical section of a simi-' lar apparatus which is to be used for greasing vertically-running ropes, and, finally, Fig. 4 shows the view of one-half of the greasingchamber provided with inlet and outlet mouthpieces. 7

Similar letters refer to similar parts throughout the several views;

The greasing apparatus consists, essentially, in the greasing-chamber A..and the grease-receiver B. The greasing-chamber A is constructed in the form of a cross-shaped piece, each of the four branches of which is an open-ended tube with the tubes all communicating with the center. The cross-shaped piece is formed of two similar half-pieces fitted one to the other and secured one to the other by screwing on one branch the pipeflange O and on the opposite branch the ring D. The other two tubular ends are provided with internal threads, and into the same are screwed the inlet-mouthpiece E and the outlet-mouthpiece F, which are also formed of two similar half'pieces fitted together. By means of screws G screwed through the respective branches the half-mouthpieces are secured to the half cross-pieces, so that when the apparatus is to be mounted around the rope to be greased the half cross-pieces are integrally secured to the half-mouthpieces,

while the mouthpieces for greasing ropes of the said opening. The groove J extends nearly from one of the fastening-bolts K to the opposite one. The slide L extends outwardly beyond the flages O and H, so that it can be operated from without. In the receiver B there is arranged upon the grease the cover M, provided with a/packing all around. In the middle of the upper side of the cover M there is hinged the fork 0, provided with holes N. Between the branches of the fork 0 there is arranged the pressinglever P, which is hinged to the upper end of the receiver B.

Figs. 1 and 2, representing an apparatus for greasing horizontally-running ropes, show a pole constructed of two telescopic tubes Q R, the inner tubeQ being closed by means of a wooden plug U and entering with its upper end into the tube-piece of the crossshaped piece A, which is held together by means of the ring D, the greasing-chamber being thus closed from below. If the apparatus is to be used for greasing vertically-running ropes, we interpose between the flange'C and the receiver '13 a curved tube S of ninety degrees, Fig. 3, and a similar curved tube between the greasing-chamber and the supp0rting-pole. The greasing-chamber A, with the mouthpieces E and F, is here turned in respect to the apparatus represented in Figs. 1 and 2 about ninety degrees. 3

The apparatus is made use of as follows: The two half-pieces of the greasing-chamber A are mounted around the rope and screwed together by means of the flange O and the ring D. To the flange G is directly screwed the grease-receiver B when the apparatus is destined for greasing horizontally-running ropes, or a curved tube of ninety degrees is interposed when vertically-running ropes are to be greased, or a curved tube of forty-five degrees when the rope to be greased is running in an inclined direction. Into the tubepiece, held together by means of the ring D, enters the upper end of the telescopic tube Q, closed by the wooden plug U in order to have a pole for the apparatus. In cases where a curved tube is used above the chamber A a corresponding one is added below the same. The mouthpieces E and F are screwed into the free opposite tubular ends of the greasingcharnber. When all this is done, we make the rope run through the apparatus, while by means of the lever 'P the cover M is pressed downwardly into the grease-receiver, whereby the grease is pressed from the grease-receiver B into the greasing-chamber A, where it enters in consequence of the great compression into the rope.

At the outlet of the outlet-mouthpiece F, which is provided, like the inlet-mouthpiece, with a conical channel, there will be arranged a leather ring or curved plate-springs T, as is shown in the annexed drawings, in order to retain the excess'of grease drawn through by the rope.

In order to be able to grease at the same time several ropes running one beside the other, we will make the greasing-chamberA of several compartments, into which the grease is pressed from the common grease-receiver B through just as many channels.

What We claim is- In an apparatus for greasing ropes the combination of a greasing-chamber A constructed of two similar half-pieces, forming a crossshaped piece consisting of four tubular branches,a pipe-flange O and a ring D,screwed on two opposite branches, a grease-receiver 13 screwed to the said pipe-flange O, a two-part inlet-mouthpiece E and a two-part outletrnouthpiece F to be screwed into the two op posite free branches of the said greasingchamber A and provided with conical channels, all essentially as described and for the purpose specified.

In witness whereof we have hereunto set our hands in presence of two witnesses.
